“Why can those smart people be so good, and the gap between people can be so big? Is it because the brain structure is different?”
This question is very interesting. Today I will tell you what is going on.
The smarter the person, the more efficient the brain works
In fact, as early as the 1980s, studies have found that people with higher IQs have a lower energy metabolism rate in the cerebral cortex when performing cognitive tasks. That is to say, smart people consume less energy when thinking about problems.
Based on this, some people hypothesize that the reason why smart people can be more focused and lasting than us may not be because they work harder than others, but because their brains work more efficiently, the so-called “neural efficiency hypothesis” )”.
This speculation was confirmed in 2018. The team of Professor Erhan Genc from the Ruhr University in Bochum, Germany found that the brain neurons of smart people are more efficiently and concisely connected to each other.
In other words, the smarter the person is, the more efficient the brain is and the lower the energy consumption for processing the same task. Therefore, it is less likely to trigger the brain’s negative feedback mechanism (feeling tired), so it can support higher working memory, more threaded tasks, longer focus.
This phenomenon may be a bit counter-intuitive, because we usually think that there should be more messy neural connections in the brain of smart people. Otherwise, how could they come up with several solutions so easily by looking at the problem?
But in this regard, we can actually refer to the brains of children around 3 years old, which have far more synaptic connections than adults. However, as they learn and grow older, these synaptic connections will be constantly “pruned”, but instead This is to improve the efficiency of our thinking. The brain is doing “subtraction” to remove useless connections.
In layman’s terms, you and a smart person run the same App, you account for 90% of the memory, and people only use 40% of the memory. You have tried your best, and he even has spare time to play a game. The reality is so cruel.
Smart people are born?
Does that mean that smart people are born and we are powerless? In fact, it is not completely “innate determinism.”
As we continue to read and study in a particular field, our brain’s synaptic plasticity in this area will increase. In our areas of expertise, our brain related areas will be like the brains of smart people.
An experienced London taxi driver was found to have greater gray mass in the posterior hippocampus (the hippocampus is an important brain area for spatial navigation, and the posterior hippocampus is more involved in the coding of spatial navigation than the front side).
The volume of gray matter in the brain regions of professional typists related to coding motor tasks (such as the motor cortex, prefrontal cortex, and cerebellum) increases.
In the primary sensory motor cortex of the brain of violinists and other string players, the area representing the left hand is larger.
Therefore, learning is useful, and genius is not absolute.
